BTN7960BAUMA1 High-Current Half-Bridge Motor Driver IC: Powering Modern Motion Control Systems

The BTN7960BAUMA1 is a high-performance, high-current half-bridge driver integrated circuit (IC) from Infineon Technologies, designed to meet the rigorous demands of modern automotive and industrial motor control applications. This robust device integrates a P-channel high-side MOSFET and an N-channel low-side MOSFET in a single package, forming a complete half-bridge stage capable of handling significant power with high efficiency.

Engineered for DC motor control, solenoid actuation, and other inductive loads, the BTN7960B stands out for its impressive current handling capability, supporting continuous currents up to 43A and peak currents up to 75A. This makes it an ideal solution for driving motors in applications such as electric power steering (EPS), throttle control, hydraulic pumps, and heavy-duty industrial automation. Its high-current capacity eliminates the need for multiple parallel devices in many cases, simplifying board design and saving valuable space.

A key feature of this IC is its integrated driver and MOSFET combination. This monolithic design reduces the number of external components required, enhancing system reliability while minimizing the overall footprint. The device includes crucial protection features that are essential for robust operation in harsh environments. These include overtemperature protection, which shuts down the IC if the junction temperature exceeds a safe threshold, and undervoltage lockout (UVLO) that disables the output if the supply voltage is too low. Furthermore, it offers protection against short circuits to ground and supply, as well as overcurrent conditions, ensuring the longevity of both the driver and the connected load.

The interface is designed for simplicity, accepting standard TTL or CMOS-level input signals from a microcontroller (MCU) to control the high-side and low-side switches. An enabledisable pin provides an additional layer of control. The diagnostic feedback feature, through a status flag, allows the MCU to monitor the health of the system, reporting faults such as overtemperature or short circuits, which is critical for implementing fail-safe operational strategies.

ICGOODFIND: The BTN7960BAUMA1 is a cornerstone power IC for engineers designing high-reliability, high-power motion systems. Its exceptional integration of power, protection, and diagnostics in a single package makes it a superior choice for demanding automotive and industrial applications, streamlining design and enhancing system resilience.
